A rotary mower is a type of agricultural machine used to cut crops such as grass and clover in the field. The machine uses rotating blades or discs to cut the vegetation close to ground level. Rotary mowers are known for their efficiency and ability to cover large fields quickly.

The main difference between a rotary mower and a sickle bar mower lies in their cutting mechanisms. A rotary mower uses rotating discs or knives that spin rapidly to cut crops, making it highly effective for handling large fields and thick vegetation. A sickle bar mower, on the other hand, uses a back-and-forth motion with a series of blades that move reciprocally to cut the crops. Sickle bar mowers are generally gentler on plants and are better suited for more delicate crops.

A rotary mower is primarily used during the harvesting season to cut crops such as grass, clover, and other forage plants. The machine is ideal for quickly processing large fields and ensuring that crops are cut evenly and efficiently. Rotary mowers are commonly used when fast and effective harvesting of hay and silage is required.

A mower knife is a component of a sickle bar mower used to cut crops. The mower knife consists of a series of sharp blades that move back and forth to slice through plant material. The reciprocating motion creates a cutting effect that allows crops to be cut close to ground level. The mower knife is crucial for the machine’s performance and requires regular maintenance and sharpening.

To ensure proper use of a rotary mower, follow these steps:

Read and follow the manufacturer’s manual and safety instructions carefully.
Check that the blades are sharp and in good condition before use.
Adjust the cutting height to suit the type of crop being harvested.
Operate the machine at a steady speed and avoid sudden movements that could damage the machine or crops.
Regularly maintain the machine by lubricating moving parts and replacing worn or damaged components.

Several essential wear parts and spare parts are available for rotary mowers and sickle bar mowers, including:

Blades and knives: These are the most critical wear parts and require regular inspection and replacement to ensure effective cutting.
Drive belts and chains: Used to transfer power from the tractor to the cutting mechanism and should be replaced when worn.
Bearings and bushings: Ensure smooth movement and reduce friction in the machine’s moving parts.
Guards and covers: Protect the operator and machine from flying debris and prevent damage.
Support feet and wheels: Help adjust and stabilize the machine during operation.

Regular inspection and maintenance of these parts are essential to keep rotary mowers and sickle bar mowers in optimal condition and extend their lifespan.
